The Bengali is a bird that likes to stroll over the open grassland. The adult has a mottled gray plumage and a darker underside. The beak is pink as well as the contour of the eyes. The eyes are sharp and clear.
Like the Serinus, the Bengali is often trapped by a glued stem fixed by mischief children. The Bengali eats grass seeds like the “fatak”. Stems found in the same fields are suitable nest material for the coupling season.
Bengalis have two-chambered nests. One of them provides habitat for the female and the offspring, the other one is the male’s nest. The male will help incubate the eggs (a clutch of four to five eggs), placed in the principal nest. Another kind of bird called the Red Munia used to live on the island, but he disappears at the end of the 19th century because of the cyclones. However, the Bengali lives along with a bird about the same size, the Scaly-breasted Munia (known as “Pingo”) who has a scaly pattern above and 'black and white 'chess board' on sides of the neck. Even if these two birds are similar, the do not have the same social behaviour.
